Trigger Point Injections

A trigger point injection (TPI) is an injection that is given directly into the trigger point for pain management. The injection may be an anesthetic such as lidocaine (Xylocaine) a mixture of anesthetics, or a corticosteroid (cortisone medication) alone or mixed with lidocaine.

Are trigger point injections nerve blocks?

Trigger point injections are not truly nerve blocks; rather they are muscle blocks. Muscles that are chronically tense or in spasm become tender and painful. The pain triggers more spasm and a vicious cycle develops. Physical therapy and exercise are the primary treatments, but injections into the muscle can help to break the vicious cycle.

Do trigger point injections work immediately?

Some patients will experience immediate relief, however, it usually takes 24 to 72 hours for the effects of the steroid medication to take effect and it may be up to 1 week before the maximum benefits are achieved. Trigger injections target the pain being caused by muscular problems.

Are trigger point injections worth it?

Trigger point injections are a viable option to treat referred pain and reduced functionality associated with muscle tenderness. These injections calm irritated nerves, take care of muscle weakness and improve the range of motion and posture.
